HOISTING DEVICE.

To all whom it may concern:

Be it known that we, GrrAnLns hurts and Crnus E. NELsoN, citizens of theUnited States, residing at Darlington, in the county of Lafayette andState of lVisconsin, have invented new and useful Improvements inHoisting Devices, of which the following is a specification.

This invention relates to hoisting devices, and contemplates a structureprimarily intended to facilitate the handling of hogs on a farm whenbutchering.

More specifically stated, the invention contemplates the provision of adevice adapted to be pivotally mounted upon the door frame of a barn orthe like, and constructed to raise and support a hog suspendedtherefrom, outside the barn to allow the hog to cool after having beendressed, and subsequently swung within the barn with the minimum of timeand effort.

The nature and advantages of the invention will be better understoodwhen the fol lowing detailed description is read in connection with theaccompanying drawings, the invention residing in the construction,combination and arrangement of parts as claimed.

In the drawings forming part of this ap plication, like numerals ofreference indicate similar parts in the several views, and whereinFigure 1 is a side elevation of the device showing how it is mountedupon the door frame of a building.

Figure 2 is a sectional view taken on line 2-2 of Figure 1.

Figure 8 is a sectional view taken on line 33 of Figure 1.

Figure 4: is a detail sectional view through the connection between thearm and bracing elements.

The device forming the subject matter of this invention essentiallyincludes a post or u u-ight which is adapted to be arranged within thedoor frame of a build ing, and mounted for rotation, so that thesupporting and raising device can be swung either to a position outsidethe building or inside the building as the occasion may require. Forthis purpose the upright 10 is provided with trunnions 11 and 12respectively, the former being journaled in the top of the door frame asclearly shown in Figure 1, while the latter is journaled in thehorlzontally disposed 1 Application filed June 2, 1924. Serial No.717,399.

branch 13 of the substantially L-shapcd bracket 14 which is secured toone side of the door frame in any suitable manner. Projecting at a rightangle from the upper. end of the standard or upright 10 is a supportingarm 15 which is suitably braced by diagonally arranged bracing elements16 having their upper extremities secured to the opposite sides of thesupporting arm 15 as shown in Figuret, while the lower ends of thesebracing elements are secured in any suitable manner to the base plate 17utilized to support the raising and lowering mechanism upon the uprightor standard 10.

The plate 17 is arranged against the standard 10 and has one siderecessed as at 18 to conform to the curvature of the upright 1O asclearly shown in Figure 2. The plate 17 is held fixed to the upright 10by means of U-shaped clamps 19 which straddle the upright 10, and havetheir extremities passed through openings in the plate 17 as clearlyillustrated. Bolted on the plate 17 is the attaching base portion 20 ofa suitable bracket including spaced parallel portions 21, which portionsterminate to provide spaced pairs of bearings 22 and 23 respectively. Journaled between the bearings 22 is a drum 24 to which a hoisting cable25 is terminally secured, and adapted to be wound about and unwound fromthe drum. This cable 25 is trained over idle pulleys 26 suspended fromthesupporting arm 15, and is then formed to provide a loop 27, the freeend of which is secured to the outer end of the supporting arm 15 as at28. This loop supports the movable sheave block in the ordinary wellknown manner. Keyed upon the shaft 30 with the same key 31 employed tohold the drum 24 thereon, is a gear 32, which meshes with a small gear33 keyed upon a stub shaft 34, which latter shaft is equipped with ahandle 35. The shaft 34 is journaled in the bearing 3 above referred to.Manifestly by turning the handle 35 in one direction the cable is woundabout the drum 2 L, thereby elevating the movable sheave 29, and whenthe handle is rotated in an opposite direction, the cable is unwoundfrom the drum 24 and the movable sheave lowered. The structure isparticularly advantageous for the use above outlined, in that a hog canbe easily and conveniently raised to an elevated position and suspendedfrom the sheave block outside the barn or building, and allowed to coolafter having been dressed. Pivoted on one of the parallel portions 21 ofthe bracket above referred to is a pawl 36 which can be convenientlyswung into active engagement with the gear 32, to prevent retrogrademovement of the drum and thus hold the sheave block 29 at any desiredheight. After the hog has been cooled, the entire supporting strue--ture can be easily and conveniently swung through the door opening; tothe inside of the building, this being permitted by the fact that theupright or post 10 is mounted for rotation'within the door frame asshown in Figure 1.

WVhil'e it is believed that from the foregoing description, the natureand advantages of the invention will be readily apparent, we desire tohave it understood that we do not limit ourselves to what is hereinshown and described and that such changes may be resorted to whendesired as fall within the scope of what is claimed.

What we claim is:

Means for supporting the crane on the door frame of a building, saidmeans comprising a bracket secured to the door frame, a: post journalledbetween the bracket and the upper part of said frame, a plate having aconcaved portion at one side to accommodate itself and said post,U-shaped clamps embracing the posts and passed through saidplate forholding the latter attached to the post, and said plate also includingan operating mechanism for the crane as and for the purpose specified.

In testimony whereof we afiix our signature.
